Anybody can make biodiesel. It's easy, you can make it in your cooking area-- and it's BETTER than the petro-diesel fuel the big oil business sell you. Your diesel motor will run better and last longer on your home-made fuel, and it's much cleaner-- better for the environment and much better for health.

If you make it from used cooking oil it's not only cheap however you'll be recycling a problematic waste product. Most importantly is the GREAT feeling of liberty, self-reliance and empowerment it will offer you. Here's how to do it-- everything you require to understand.

Straight veggie oil fuel (SVO) systems can be a tidy, efficient and affordable alternative. Unlike biodiesel, with SVO you need to customize the engine. The finest method is to fit an expert singletank SVO system with replacement injectors and glowplugs optimised for veg-oil, along with fuel heating.

With the German Elsbett single-tank SVO system for instance you can use petro-diesel, biodiesel or SVO, in any combination. Just launch and go, stop and turn off, like any other cars and truck. Journey to Forever's Toyota TownAce van utilizes an Elsbett single-tank system. More

There are also two-tank SVO systems which pre-heat the oil to make it thinner. You need to start the engine on common petroleum diesel or biodiesel in one tank and then change to SVO in the other tank when the veg-oil is hot enough, and change back to petro- or biodiesel before you stop the engine, or you'll coke up the injectors.

3. Biodiesel or SVO?

Biodiesel has some clear advantages over SVO: it operates in any diesel, with no conversion or modifications to the engine or the fuel system-- just put it in and go. It likewise has better cold-weather properties than SVO (but not as good as petro-diesel-- see Using biodiesel in winter). Unlike SVO,

it's backed by numerous long-lasting tests in numerous nations, including millions of miles on the roadway.

Biodiesel is a tidy, safe, ready-to-use, alternative fuel, whereas it's fair to say that many SVO systems are still experimental and require further development.

On the other hand, biodiesel can be more costly, depending just how much you make, what you make it from and whether you're comparing it with new oil or used oil (and depending on where you live). And unlike SVO, it has to be processed initially.

But the large and quickly growing around the world band of homebrewers don't mind-- they make a supply weekly or as soon as a month and soon get utilized to it. Many have been doing it for years.

Anyway you have to process SVO too, especially WVO (waste veggie oil, used, prepared), which lots of people with SVO systems due to the fact that it's cheap or complimentary for the taking. With WVO food particles and pollutants and water should be eliminated, and it most likely ought to be deacidified too. Biodieselers say, "If I'm going to have to do all that I might also make biodiesel instead." But SVO types scoff at that-- it's much less processing than making biodiesel, they say. To each his own.
